SUNSPOT MONITORING – JUNE 5, 2020

645 1024 alsadeemadmin

Here are today’s solar images taken from Al Sadeem Observatory, June 5, 2020.

The sky was generally clear with intermittent light to moderate winds which provided good transparency but average seeing at the time these images were taken.

More sunspot development was observed in the leader section of AR2765 (Modified Zurich/Mcintosh sunspot configuration: Csx/alpha) but has remained stable and generally inactive over the past 24 hours. A weak B-class solar flare associated with it was recorded by space weather agencies. The latest sunspot number (based on visual count and Wolf number calculation) is 13. Other than that, the Sun exhibited small plages and faculae associated with former AR2764 transiting the solar disk and an elongated stable filament at the far southern hemisphere; as distinctively captured in H-alpha imagery.

Space weather agencies* forecast solar activity to remain at very low levels with chances of weak X-ray fluxes or flares up to B-class (possibly up to C-class) intensity, mainly from AR2765. Close monitoring is being conducted by numerous space weather agencies for any significant development.

Equipment used are Skywatcher 120mm refractor telescope with Baader filter and unmodified Canon EOS 1D Mark IV DSLR camera for visible imagery and Lunt H-alpha solar telescope and QHYCCDIII mono camera for H-alpha imagery, mounted on Skywatcher EQ6 Pro. Pre-processing of visible solar images was performed in PIPP, stacking in Autostakkert, slight wavelet adjustments in Registax 6, and post-processing in Adobe Photoshop CC.
